create procedure proc_page_withtopmax
(
 @pageIndex int,--页索引
 @pageSize int,--每页显示数
 @pageCount int output,--总页数,输出参数 
 @totalCount int output--总条数
)
as
begin
set nocount on;

declare @sql nvarchar(1000)
set @sql=select top 10 *  from tb_testtable where (id> (select max(id) from (select top +str((@pageIndex-1)*@pageSize)+ id from tb_testtable order by id) as temp)) order by id
execute(@sql)

declare @sqlRecordCount nvarchar(1000) --得到总记录条数的语句
set @sqlRecordCount=Nselect @recordCount=count(*) from tb_testtable 
declare @recordCount int --保存总记录条数的变量
exec sp_executesql @sqlRecordCount,N@recordCount int output,@recordCount output 

if( @recordCount % @pageSize = 0) --如果总记录条数可以被页大小整除 
set @pageCount = @recordCount / @pageSize --总页数就等于总记录条数除以页大小 
else --如果总记录条数不能被页大小整除 
set @pageCount = @recordCount / @pageSize + 1 --总页数就等于总记录条数除以页大小加1 

set @totalCount = @recordCount

set nocount off;
end

--数据库中执行该存储过程
declare @pageCount int, @totalCount int

exec proc_page_withtopmax 2,95955,@pageCount output,@totalCount output

select 总页数:+str(@pageCount)
select 总条数:+str(@totalCount)

C# 代码调用该带输入输出参数的分页存储过程

  public static DataSet GetRecordByPage( int pageSize, int pageIndex, out int pageCount, out int totalCount)
        {
            DataSet ds = new DataSet();
            try
            {
                using (SqlConnection conn = new SqlConnection(@"server=;database=data_test;uid=; pwd=;"))
                {
                    SqlCommand cmd = new SqlCommand();
                    cmd.Connection = conn;
                    cmd.Parameters.Add(new SqlParameter("@pageSize", SqlDbType.Int));
                    cmd.Parameters.Add(new SqlParameter("@pageIndex", SqlDbType.Int));
                    SqlParameter param = new SqlParameter("@totalCount", SqlDbType.Int);
                    param.Direction = ParameterDirection.Output;
                    cmd.Parameters.Add(param);

                    SqlParameter param1 = new SqlParameter("@pageCount", SqlDbType.Int);
                    param1.Direction = ParameterDirection.Output;
                    cmd.Parameters.Add(param1);

                    cmd.Parameters[0].Value = pageSize;
                    cmd.Parameters[1].Value = pageIndex;
                    cmd.Parameters[2].Value = 0;
                    cmd.Parameters[3].Value = 0;

                    cmd.CommandType = CommandType.StoredProcedure;
                    cmd.CommandText = "proc_page_withtopmax";
                    cmd.CommandTimeout = 180;

                    SqlDataAdapter adapter = new SqlDataAdapter();
                    adapter.SelectCommand = cmd;

                    DataSet source = new DataSet();
                    adapter.Fill(ds);
                 
                    object o = cmd.Parameters["@totalCount"].Value;
                    totalCount = (o == null || o == DBNull.Value) ? 0 : System.Convert.ToInt32(o);

                    object b = cmd.Parameters["@pageCount"].Value;
                    pageCount = (b == null || o == DBNull.Value) ? 0 : System.Convert.ToInt32(b);
                }
            }
            catch (SqlException e)
            {
                throw e;
            }
            return ds;
        }

    }
